Ingredients
Method
Prepare the Homemade Salsa Verde
- Heat the olive oil in a medium saucepan over medium heat. Add the diced onion and cook until softened, about 4 minutes.
- Stir in the minced garlic, chopped tomatillos, and poblano pepper. Cook for 5 minutes, stirring frequently.
- Pour in the vegetable broth and bring the mixture to a simmer. Cover and cook for 10 minutes until the tomatillos soften.
- Remove from heat and transfer the mixture to a blender. Add the cilantro, cumin, and chili powder. Blend until smooth. Season with salt and pepper to taste. Set aside.
Preheat the Oven
- Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish lightly with cooking spray or a small amount of olive oil.
Assemble the Casserole
- Spread a thin layer of salsa verde at the bottom of the prepared baking dish.
- Place a layer of corn tortilla halves to cover the bottom of the dish. Overlap them slightly for full coverage.
- Spoon a third of the black beans, quinoa, sweet potato, spinach, and red onion evenly over the tortillas.
- Drizzle with a generous amount of salsa verde and sprinkle with shredded cheese.
- Repeat the layers (tortillas, fillings, sauce, and cheese) two more times, finishing with a top layer of tortillas, sauce, and a final sprinkling of cheese.
Bake the Casserole
- Cover the baking dish with aluminum foil and bake for 25 minutes. This step helps the flavors meld together and prevents the cheese from browning too quickly.
- Remove the foil and bake for an additional 10–15 minutes, or until the cheese is melted and bubbly.
- For an extra golden top, broil the casserole on high for 2–3 minutes, keeping a close eye to avoid burning.
Garnish and Serve
- Allow the casserole to cool for 10 minutes before slicing. This helps it set and makes serving easier.
- Garnish with crumbled queso fresco, fresh cilantro, and diced jalapeño if desired.
- Serve with a side of sour cream, guacamole, or a fresh lime wedge.
